To all whom it may concern:

Beit knownthat I,.JAooB A. FIESER, a.

citizen of the United States, residing at Larimer, in the county ofWVestmoreland and State of Pennsylvania, have invented.

certain new and useful Improvements in .Hose-Couplings; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itiimprovements in swiveled couplings for hose pipes forming means wherebythe difierent sections of the pipe may be turned to prevent twisting.

The invention consists further of other details of construction andcombinations and arrangements of parts which will be hereinafter fullydescribed, shown .in the accompanying drawings and then specificallydefined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figuretie a plan view of my improved coupler. Fig. 2 is a central longitudinalsectional view, and Fig.3 is a detail view of a clamping member, formingmeans for holding the hose upon the coupler head.

Reference now being had to the details of the drawings by letter, A;designates a cou-' pler head provided with a tapering portion B,terminating at its inner end in a shoulder C which forms the forwardedge of an annular groove F, the bottom of which is in' clined. Saidcoupler head has a contracted shank portion H having circumferentialshoulders thereon, said shank portion adapted to receive the .end K ofahose pipe. The circumference of the coupler head has holes 0 formedtherein, and N, N designate semi-cylindrical clamping plates, eachhaving shoulders upon its inner' face adapted to conform to andcooperate with the shoulders formed upon the contracted portion of thehead to clamp andlhold the hose pipe securely to the coupler head. Theinner surface of each clamping member is beveled as atQ, to. receive theinner flaring end of the hose pipe, and L, L designatehooks whichproject from the tapering portion of the clamping member and adapted toengage Specification of Letters Patent.

said holes in the coupler head in the manner shown clearly in thedrawings. It will be noted that two of said clampingmembers are ofsimilar construction and each provided with hooks engaging the couplerhead and the circumference of each clamping member has 1 an annularrecessI formed therein for the reception of a resilient band B adaptedto hold the two clamping sections in clamping relation with-the end ofthe hose which telescopes over the contracted portion ofthecouplerhead'. The coupling end of thehead A has a chambered portion inwhich is positioned. a washer A and against which latter the end of theadjacent coupler head is adapted to contact.

The second coupler head is designated in the drawings by letter T andhas at its coupling end a contractedextension T which is adapted totelescope within the chambered portion ofthe other coupling head, and awasher T .is mounted about the inner end of said contracted extensionand against which the washer within said chambered portion of the head Ais adapted to contact recesses formed in the clamping member to hold thesame in engagement with the hose. Said head T is provided with a seriesof elongated slots formed in the circumference thereof, and J designatehooks having resilient shankportions with inclined portions J adapted.to contact with the inclined portion B ofthe coupler head A when the twocoupler heads come together and for the purpose of spreading the hookswhich, after the latter pass by the inner end of the inclined'portionsB, engage. the shoulder upon the head A, as illustrated in the drawings.

By the provision of a coupler head made in accordance with my invention,it will be noted that sections of hose may be connected together and onesection rotate independent of the other, through the medium of theswiveled connections shown, thus preventhaving serrations thereon,semi-cylindrical bers, which latter may be easily removed by simplydetaching the resilient bands and theclamping members.

What I claim to be new is A hose coupling comprising a coupler headhaving a contracted extension at its coupling end, a second couplinghead recessed at its end for thev reception of the contracted end of theother coupler, means for fastening the coupler heads together, portionsof the circumference of said heads shells with the inner concavedsurfaces serrated and forming jaws to cooperate with the serrations uponthe heads to hold the ends of hose pipes u on the coppler heads, hooksfastened to sai shells and projecting beyond the inner ends thereof andadapted to engage holes formed in the coupler head, as set forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

JACOB A, FIESER.
